These weights are 12 utilized by tasks which have set their mempolicy to 13 MPOL_WEIGHTED_INTERLEAVE. 14 15 These weights only affect new allocations, and changes at runtime 16 will not cause migrations on already allocated pages. 17 18 The minimum weight for a node is always 1. 19 20 Minimum weight: 1 21 Maximum weight: 255 22 23 Writing an empty string or `0` will reset the weight to the 24 system default. The system default may be set by the kernel 25 or drivers at boot or during hotplug events. 26
